1

what occurs on the 1st clinical visit?

- history and examination
- treatment planning
- primary impression

2

what are some components of the patient history?

- previous dental history
- previous medical history

3

history & exam: what needs to be asked for denture making?

- were there previous attempts of denture making?
- were they successful?
- how long were they worn?
- what does pt think?

4

examination: what should be assesed?

- soft tissues: are they healthy? does the pt require specific management before making new dentures?
- full dental charting, BPE, examination and drawing of current dentures
- examine occlusion: any index teeth?

5

what are index teeth?

points of contact of opposing teeth, indicating intercuspal position

6

what occurs during lab stage 1?

- production of primary casts (study casts)
- production of record blocks (occlusal rims)

7

what are occlusion blocks/occlusal rims?

occlusion blocks consist of wax rims attached to well-fitting trial denture bases
they help to create maxillomandibular relation records, help to arrange teeth

8

what happens on the 2nd clinical visit? requirement depends on?

occlusion stage (if required). depends on how many teeth the patient has and how clear the occlusal relationships are

9

what determines the need for an occlusion visit?

whether the casts can be articulated without the need for record blocks

10

record blocks are used for?

to record the correct occlusal vertical dimension when there is lack of sufficient tooth contact

11

what happens during lab stage 2?

articulation of casts
design of partial denture
surveying
construction of special trays

12

design of partial dentures: require? (4)

- surveyed casts
- examination of occlusion
- reference to previous design of dentures
- information of history and examination e.g. prognosis of teeth

13

surveying: gives information on?

1. path of insertion of denture
2. areas around the teeth that may stop the denture being seated
3. areas around the teeth that are useful for holding the denture in

14

design of partial dentures: what must happen regarding the casts beforehand?

casts must be articulated before partial dentures can be designed
(may or may not require occlusion stage, depending on patient and how much teeth present)

15

3rd clinical visit: what happens?

1. review and discuss design of dentures with patient
2. tooth modifications/preparations e.g. rest seats or composite additions
3. secondary impressions in special trays
4. choose artificial teeth

16

what happens during lab stage 3?

1. preparation of secondary (working) casts
2. construction of casting
3. setting of artificial teeth

17

4th clinical visit: what happens?

try in stage - trial insertion
if there is metal casting as part of the denture, will need to be assessed for fit

18

try in: what to take note and check for?

- check lab work
- insert try-in & check for:
extensions
adaptation
retention
occlusion & tooth position
appearance

19

lab stage 4?

- processing of denture
- conversion of wax parts into polymethylmethacrylate
- artificial teeth secured to denture

20

5th clinical visit? what to assess?

fitting of prostheses
assess similar factors as trial insertion stage:
check lab work, fit denture and check:
extensions, adaptations, retention, occlusion, appearance
+ give instructions on care

21

6th visit of patient?

ease pt
- listen for pt comments
- examine mouth
- adjust denture as required
- put pt on recall
